摘要：宽恕政策是卡特尔执法的有效政策工具,它有利于破坏卡特尔的稳定性,有利于提高卡特尔的执法效率。设计合理的规则是宽恕政策有效发挥作用的基础,具体、确定、透明是宽恕政策的基本要求。宽恕政策的实施效果与卡特尔的立法、执法状况密切相关,严厉的法律制裁、坚定的执法态度和有力的执法措施能够有效促进宽恕政策的实施。为了加强卡特尔执法,我国反垄断执法机构应当根据《反垄断法》的有关规定尽快出台宽恕政策。

摘要：The solubility of ammonium tungstate in a special hydrothermal condition is exploited to synthesize uniform microspheres of Ce-Cu-W-O *** to their W-undoped counterparts,they possess more Ce^3+ and oxygen vacancies,thereby promoting oxygen *** formed rich WO3 surface can effectively provide acid sites,which is helpful for adsorption of vinyl chloride and interrupting the C-Cl *** addition,the presence of WO3 induces the formation of finer CuO nanoparticles with respect to the traditional coprecipitation method,thereby resulting in a better *** from both the enhanced acidity and reducibility,the Ce-Cu-W-O microspheres deliver excellent low-temperature vinyl chloride oxidation activity(a reaction rate of 2.01×10^-7 mol/(gcat·s)at 250℃)and high HCl ***,subtle deactivation occurs after the three cycling activity tests,and a stable vinyl chloride conversion as well as mineralization are observed during the 72-h durability test at 300℃,which demonstrates good thermal *** strategy can provide new insights into the design and synthesis of metal oxides for catalytic oxidation of chlorinated volatile organic compounds.

摘要：自然场景下的文本区域形状复杂多变,直接使用轮廓坐标描述文本区域会使得建模不充分,导致文本检测准确性低。针对自然场景下文本区域不规则的问题,提出了一种基于Deformable DETR的任意形状文本检测模型,不同于传统的直接预测轮廓点的方法,使用B-样条对文字区域进行建模使得文本轮廓平滑精确的同时减少了需要预测的参数。提出的文本检测模型无需手工设计锚点、区域建议等组件,极大地简化了模型设计并提高了通用性。提出的模型在无需额外数据集的情况下在任意形状文本数据集CTW1500和Total-Text上的平均精度(F值)分别达到了85.4%和85.0%,证明了模型的有效性。
